Pivotable Holding Element for Weaving Accessory Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawing-in machines for weaving accessories face inefficiencies in transporting weaving accessories over long distances, particularly drop wires and healds, which are often transported slowly and require multiple holding elements, leading to reduced reliability and productivity.
Innovation Solution
A handling device with pivotable holding elements that move weaving accessories from a pick-up position to a drawing-in position and back, utilizing a combination of pivoting movements around two axes and spring elements for secure transport without releasing the accessories, allowing for efficient and reliable handling over extended distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If weaving accessories are transported over long distances on rail-like guideways, then the transport distance is increased, but the transport speed decreases and productivity is reduced
Solution Approach 1:
The holding element is designed to be pivotable around a first axis, allowing it to dynamically change its orientation and position. This enables the holding element to efficiently pick up, transport, and release weaving accessories over long distances without requiring slow rail-like guideways, thus resolving the contradiction between transport distance and productivity
Solution Approach 2:
The transport system is divided into discrete holding elements that can independently pivot and move weaving accessories. Instead of continuous transport on fixed guideways, the segmented holding elements provide flexible, high-speed transport, eliminating the speed limitation of traditional continuous transport systems
2Reliability
If multiple holding elements are used to transport weaving accessories, then the reliability of transport is improved, but the device complexity increases
Solution Approach 1:
A single holding element is designed with multi-functionality, being able to pivot around the first axis to perform pickup, transport, and release operations. This universal design eliminates the need for multiple specialized holding elements, maintaining reliability while reducing device complexity
Solution Approach 2:
The functions of multiple holding elements are merged into a single pivotable holding element. By combining the pickup, transport, and release functions into one element that can reposition itself through pivoting, the system achieves the same reliability with fewer components, thus reducing complexity
3Adaptability or versatility
If weaving accessories are released and rehandled multiple times, then the flexibility of handling is improved, but the time consumption increases and productivity decreases
Solution Approach 1:
The pivotable holding element maintains continuous contact with the weaving accessory throughout the entire transport process. By pivoting smoothly from pickup to release positions without releasing the accessory, the system eliminates interruptions and time losses associated with multiple handling operations, while still providing flexible adaptation
4Length of moving object
If additional holding elements or guideways are added to extend transport distance, then the transport capability is improved, but the device complexity and cost increase
Solution Approach 1:
The holding element uses pivoting motion around the first axis to achieve extended transport capability. This dynamic repositioning allows a single holding element to cover long distances without requiring additional holding elements or complex guideways, thus extending transport distance while minimizing structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures reliable and fast transport of weaving accessories by maintaining contact throughout the process, increasing productivity and reducing the need for additional holding elements or guideways, enabling efficient handling from pick-up to hand-over positions.
Implementation Method 1
The at least one holding element comprises a contact surface for a weaving accessory. The greater extension of the contact surface defines the longitudinal direction of the holding element and the lesser extension of the contact surface defines the lateral direction of the holding element.

AI summary
A device and a method for handling weaving accessories are described herein. The device comprises at least one holding element for a weaving accessory. The at least one holding element comprises a contact surface for a weaving accessory. The greater extension of the contact surface defines the longitudinal direction of the holding element and the lesser extension of the contact surface defines the lateral direction of the holding element. The at least one holding element is arranged pivotably around a first axis, which extends at a right angle to the holding element's longitudinal direction. A weaving accessory at the holding element's contact surface can thus be moved from a pick-up position to a drawing-in position by pivoting the holding element around the first axis.
